I've never done my own decals, but Wayne Stevens, Jr., - wayne1320, or is he 1320wayne does outstanding decals. He's building the Cobra drag racer in the WIPS. I don't know if he makes them for others though.

Yepper, I'd see if one of the guys on here would be willing to print a couple seat covers out for ya. I'd offer, but I don't have a working printer these days. But I'd bet someone would do it, especially if you sent them the decal film for their printer.

It's really coming together. Can't wait to see it after you lay them flames down.
Not sure if you figured out the seat cover thing but couldn't you just use a piece of scrap material with the same pattern on it and wrap the seats? I pretty sure they have those big rolls of material in Walmart. I would just go see if they have any scraps laying around or just buy a small amount. This way it's the same pattern and gives you the material feeling.
Just a suggestion. Anyways, nice build, keep it coming.
